Bronchitis, fever, feeling better, terrible?

Ah, yes. I'm currently tortured by bronchitis also. You see with me, I had a fever and the next day it went away but then during the night it came back. The next day my fever, again, went away but at night it came back again. This kept going on for a little more than half a week. Yes, it's normal. It will go away, then come back. All that matters is that each time the pain lessens a bit. It shouldn't be long before your fever stops coming back and the pain goes away. But you will still keep coughing for a few more days or weeks.
